Binge-watching of TV shows raises colorectal cancer riskApril 9, 2019
Long H Nguyen et al shows sedentary behavior as a contributory factor to the dramatic rise in colorectal cancer (CRC) among people under the age of 50. The study specifically looked at TV viewing time and increased risk of young-onset CRC, after adjusting for putative risk factors, including obesity and physical activity. The study subjected 89,278 American women between 25 and 42 years at the start of the study, in 1991. The research documented 118 incident cases of young-onset CRC over 22 years of follow-up. The study found that in women with 7.1–14 hours of TV watching per week had a multi-variable relative risk (RR) of 1.12, which further increased for greater than 14 hours per week. This association was observed among participants without a CRC family history and was more pronounced for rectal cancer. Overweight or obese participants were pronounced to be more susceptible. Researchers suggest further studies to be conducted to elucidate the underlying biological mechanism that may explain this phenomenon.
